"GiFi" — Short-Range, 5-Gbps Wireless For $10/Chip 190

Posted by kdawson from the can-you-say-giga dept.
mickq writes "The Age reports that Melbourne scientists have built and demonstrated tiny CMOS chips, 5 mm per side, that can transmit 5 Gbps over short distances — about 10 m. The chip features a tiny 1-mm antenna, a power amp that is only a few microns wide, and power consumption of only 2 W. 'GiFi' appears set to revolutionize short-distance data transmission, and transmits in the relatively uncrowded 60GHz range. Best of all, the chip is only about a year away from public release, and will only cost around US $9.20 to produce."

  • At first blush, it seems like this is a bluetooth replacement, until you look at the cost of the chips- almost ten dollars per unit! Wowza- that means it'll cost $15 to put it in anything.

    'Course, I don't know how expensive bluetooth chips are per unit, but I expect they're cheaper than that- especially with all the tiny USB bluetooth receivers you can find floating around for $19.99 and under these days.

    That said, what else would it really replace or be used in?

        True, but all USB 1.1 gizmos are backwards compatible with USB 2.0, and this is hardly backwards compatible with Bluetooth.

        In this case you have a totally different standard that appears to be competing not so much in the PAN area but in the wireless-USB area, and in that respect I see it competing with UWB and WUSB. However, WUSB is only 480 Mbits per second...

        That said, at the moment, WUSB seems to be a solution looking for a problem; which leads back to my original issue. Where is this going to come in handy at this price point? Nobody's going to pay upwards of $35 for a glorified USB cable.

            I've been working on a totally wireless monitor for years, and I've almost got the solution - details here [wikipedia.org].

            To make it the most efficient, I use a directed beam of energy. I also pre-convert that energy to photons before sending it, so that the monitor won't have to waste energy doing the conversion. I also pre-modulate the signal spatially so that I only send the energy needed -- again, another win for efficiency.

      That said, what else would it really replace or be used in?

      Short-range wireless video transmission, for one. From your IPTV box to your TV(s).

      Case in point: at home, we just ditched cable and DSL and switched to an optic fibre triple-play (internet/IP TV/telephone) offer, which is much cheaper. For technical reasons the main receiver box can only be located near our entrance door, while the TV sits at the other side of the house.

      Out of three possible solutions, none work well:
      -laying an ethernet cable in the ceiling is possible, but a headache
      -IP over the power lines is unreliable
      -WiFi, regardless of the flavor, doesn't provide enough bandwidth (keep in mind that the box streams several HDTV channels at once, for instance when recording one while watching another)

      So in our case, the proposed chip and protocol sounds ideal. 10m doesn't seem like a lot, but it's more than enough to cover most apartments / houses, and I expect it will be possible to get signal at much greater distances, with degraded signal. 2.5Gbps over 20m, wirelessly, would rock.

      Of course they're going to be expensive in small quantities, but if this takes off, that price will come down drastically, to something more like $1-2 per chip, which will only increase usage. $10 isn't particularly expensive for cutting edge technology like this to begin with, so it really won't make much of a difference.
